in some more detail
- what burning device you use (a 'cd burner won't play dvd's)
- what burning program you use
- what exactly happens if you try to burn a cd or a dvd
The most likely outcome of this issue is:
a. Lens cleaner doesn't help.
b. Replacing the device by a new one is the solution.
But it just might be different in your case.
My cd burner won't burn anymore. It plays dvds and cds but won't burn with itunes or mediaplayer. Could this be caused by a dirty lens?
